Take
a walk in the nature: Alongside the ocean, by a lake, up hillsides, in
the wood or in the mountains. Calm down. Look at the green trees, the
flowers and the fields. See the beauty in the nature around you. Feel
the harmony that the sounds and colours give to your mind. Feel how the
nature makes you stronger in body and mind.

The
green colour in the woods, parks and gardens makes your mind calm and
relaxed. Colours are feelings. Green gives you harmony.
